3 MODEL 3130 Downflow General Commercial Pre-Installation Check List WATER PRESSURE: A minimum of 25 pounds of water pressure is required for regeneration valve to operate effectively. ELECTRICAL FACILITIES: A continuous 115 volt, 60 Hertz current supply is required. (Other voltages available.) Make certain the current supply is always hot and cannot be turned off with another switch. EXISTING PLUMBING: Condition of existing plumbing should be free from lime and iron buildup. Piping that is built up heavily with lime and/or iron should be replaced. If piping is clogged with iron, a separate iron filter unit should be installed ahead of the water softener. LOCATION OF SOFTENER AND DRAIN: The softener should be located close to a drain. BY-PASS VALVES: Always provide for the installation of isolation and by-pass valves. CAUTION: Water pressure is not to exceed 120 p.s.i., water temperature is not to exceed 100 F, and the unit cannot be subjected to freezing conditions. INSTALLATION INSTRUCTIONS 1. Place the softener tank where you want to install the unit making sure the unit is level and on a firm base. (Maximum 7 feet apart for twin units.) 2. All plumbing should be done in accordance with local plumbing codes. The pipe size for the drain line should be the same size or larger than the drain line flow control connection. Water meters are to be installed on soft water outlets. Twin units with (1) one meter shall be installed on common soft water outlet of units. If possible, minimize height of drain line above valve. 3. Make sure that the floor is clean beneath the salt storage tank and that it is level. 4. Place approximately 1 of water above the grid plate (if used) in your salt tank Salt may be placed in the unit at this time. 5. Close softener isolation valves and open the bypass valve. Turn on the main water supply. Open a cold soft water tap nearby and let run a few minutes or until the system is free from foreign material (usually solder) that may have resulted from the installation. 6. Open the softener inlet valves and close the bypass valve. 7. Manually index the softener control into service position and let water flow into the mineral tank. When water flow stops, close inlet valve, place control in backwash position to relieve head of air, then gradually open inlet valve to purge remaining air in tank. Return control to service position. 8. Electrical: All electrical connections must be connected according to codes. Use electrical conduit if applicable. Remote meter systems and twin meter system wiring diagrams are on pages Teflon tape is the only sealant to be used on the drain fitting. The drain from twin units may be run through a common line. 10. Plug into power supply. Page 3

20 MODEL 3210 ECONOMINDER Commercial Demand Regeneration Control Timer Settings Typical Programming Procedure Calculate the gallon capacity of the system, subtract the necessary reserve requirement and set the gallons required by lifting the gallon dial and rotating it so that the number of gallons required is aligned with the white dot on program wheel gear. Release and check for firm engagement with gear. Note, drawing shows 8,750 gallon setting. The capacity (gallons) arrow denotes remaining gallons exclusive of fixed reserve. Note: To set meter capacity at initial start-up, either: 1. Rotate manual regeneration knob one full revolution. or 2. Rotate program wheel manually clockwise or counter clockwise and align white dot with capacity arrow. This procedure must be followed any time the program wheel setting is changed. How To Set The Time Of Day: Press and hold the red button in to disengage the 24 hour gear. Turn the 24 hour gear until the actual time of day is at the time of day pointer. Release the red button to again engage the 24 hour gear. How To Manually Regenerate Your Water Conditioner At Any Time: Turn the manual regeneration knob clockwise one click. This slight movement of the manual regeneration knob engages the program wheel and starts the regeneration program. The black center knob will make one revolution in the following approximately three hours and stop in the position shown in the drawing. Even though it takes three hours for this center knob to complete one revolution, the regeneration cycle of your unit might be set for only one half of this time. In any event, conditioned water may be drawn after rinse water stops flowing from the water conditioner drain line. Immediate Regeneration Timers: These timers do not have a 24 hour gear. Setting the gallons on the program wheel and manual regeneration procedure are the same as previous instructions. * 24 HOUR GEAR MANUAL REGENERATION KNOB SERVICE POSITION INDICATOR PROGRAM WHEEL RED TIME SET BUTTON WHITE DOT GALLONS LABEL * Immediate regeneration timers do not have 24 hour gear. No time of day can be set. Page 20

21 MODEL 3200 TIMER Timer Setting Procedure How To Set Days On Which Water Conditioner Is To Regenerate: Rotate the skipper wheel until the number 1 is at the red pointer. Set the days that regeneration is to occur by sliding tabs on the skipper wheel outward to expose trip fingers. Each tab is one day. Finger at red pointer is tonight. Moving clockwise from the red pointer, extend or retract fingers to obtain the desired regeneration schedule. How To Set The Time Of Day: Press and hold the red button in to disengage the drive gear. Turn the large gear until the actual time of day is at the time of day pointer. Release the red button to again engage the drive gear. How To Manually Regenerate Your Water Conditioner At Any Time: Turn the manual regeneration knob clockwise. This slight movement of the manual regeneration knob engages the program wheel and starts the regeneration program. The black center knob will make one revolution in the following approximately three hours and stop in the position shown in the drawing. Even thought it takes three hours for this center knob to complete one revolution, the regeneration cycle of your unit might be set only one half of this time. In any event, conditioned water may be drawn after rinse water stops flowing from the water conditioner drain line. SERVICE POSITION INDICATOR RED TIME SET BUTTON 24 HR. GEAR MANUAL REGENERATION KNOB SKIPPER WHEEL, 12 DAY (SHOWS EVERY OTHER DAY REGENERATION) How to Adjust Regeneration Time: 1. Disconnect the power source. 2. Locate the three screws behind the manual regeneration knob by pushing the red button in and rotating the 24 hour dial until each screw appears in the cut out portion of the manual regeneration knob. 3. Loosen each screw slightly to release the pressure on the time plate from the 24 hour gear. 4. Locate the regeneration time pointer on the inside of the 24 hour dial in the cut out. 5. Turn the time plate so the desired regeneration time aligns next to the raised arrow. 6. Push the red button in and rotate the 24 hour dial. Tighten each of the three screws. 7. Push the red button and locate the pointer one more time to ensure the desired regeneration time is correct ADJUSTABLE REGENERATION TIMER 8. Reset the time of day and restore power to the unit. IMPORTANT! SALT LEVEL MUST ALWAYS BE ABOVE WATER LEVEL IN BRINE TANK Page 21

22 MODEL 3200 & 3210 TIMER SERIES Regeneration Cycle Program Setting Procedure How To Set Regeneration Cycle Program: The regeneration cycle program on your water conditioner has been factory preset, however, portions of the cycle or program may be lengthened or shortened in time to suit local conditions & 3210 Series Timers (Figure to Right) To expose cycle program wheel, grasp timer in upper lefthand corner and pull, releasing snap retainer and swinging timer to the right. To change the regeneration cycle program, the program wheel must be removed. Grasp program wheel and squeeze protruding lugs toward center, lift program wheel off timer. (Switch arms may require movement to facilitate removal.) Return timer to closed position engaging snap retainer in back plate. Make certain all electrical wires locate above snap retainer post. Timer Setting Procedure for 3200 & 3210 Timer BRINE & RINSE SECTION (2 MIN. PER HOLE) PIN STORAGE PROGRAM WHEEL FOR CONTROL OF REGENERATION CYCLE RAPID RINSE SECTION (2 MIN. PER PIN) BRINE TANK REFILL SECTION (2 MIN. PER HOLE) How To Change The Length Of The Backwash Time: The program wheel as shown in the drawing is in the service position. As you look at the numbered side of the program wheel, the group of pins starting at zero determines the length of time your unit will backwash. FOR EXAMPLE: If there are six pins in this section, the time of backwash will be 12 min. (2 min. per pin). To change the length of backwash time, add or remove pins as required. The number of pins times two equal the backwash time in minutes. How To Change The Length Of Brine And Rinse Time: The group of holes between the last pin in the backwash section and the second group of pins determines the length of time that your unit will brine and rinse (2 min. per hole). To change the length of brine and rinse time, move the rapid rinse group of pins to give more or fewer holes in the brine and rinse section. Number of holes times two equals brine and rinse time in minutes. How To Change The Length Of Rapid Rinse: The second group of pins on the program wheel determines the length of time that your water conditioner will rapid rinse (2 min. per pin). BACKWASH SECTION (2 MIN. PER PIN) To change the length of rapid rinse time, add or remove pins at the higher numbered end of this section as required. The number of pins times two equals the rapid rinse time in minutes. How To Change The Length Of Brine Tank Refill Time: The second group of holes in the program wheel determines the length of time that your water conditioner will refill the brine tank (2 min. per hole). To change the length of refill time, move the two pins at the end of the second group of holes as required. The regeneration cycle is complete when the outer microswitch is tripped by the two pin set at end of the brine tank refill section. The program wheel, however, will continue to rotate until the inner microswitch drops into the notch on the program wheel. Page 22
